Application filed January 19,1886. Serial No.189fi07. (No model.)

To ctZZ whom it 72mg concern;

Be it known that I, GEORGE \VIARD, of Batavia, in the county of Geneseeand State of New York, have invented a new and useful lmprovement inPlows, of which the following is a specification.

This invention relates to an improvement in that class of plows commonlycalled sidehill plows, in which the point and moldboard are madereversible, so that these parts can be placed on either side of thestandard, and in which the j ointcr is so connected with the mold-boardthat the j oiuter is reversed simultaneously with the mold-board andpoint.

The object of this invention is to provide simple means for effectingthese adjustments of the mold-board, point, and jointer; and myinvention consists, to that end, ofthe improvements which will behereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, consisting of two sheets, Figure 1 is aside elevation of a plow provided with my improvements. Fig. 2 is a topplan view thereof. Fig. 3 is a vertical longitudinal section of theadjusting devices on an enlarged scale. Fig. 4: is a horizontal sectionin line a .r, Fig-3. Fig. 5 is a top plan view of the two-armed hookwhereby the mold-beard is held in position. Fig. 6 is a side elevation,and Fig. 7 is a bottom plan view of the locking-disk.

Like letters of reference refer to like parts in the several figures.

A represents the plow-beam, and A the standard, which may be constructedin one piece with the beam.

B represents the point, and B the moldboard, both formed symmetricallyon both sides oftheir central line in a well-known manner, so that theycan be arranged on either side of the standard. The mold-board andpointare pivoted to the lower end of the standard in a well-knownmanner, so that they can be swung underneath the standard from one videdon its front side with a central ear, (I, which is secured to thestandard or beam by a bolt, (1'. 7

E represents the duplex hook whereby the mold-board is secured in place.The hook E is provided with two arms, j", having clawsf at their ends,which engage with one of the lugs f formed on the rear side of the moldboard,in a well-known manner. The hook E is pivoted to the under side ofthe cross-piece l) by a bolt, 9. .The cross'piece D is inclinedforwardly, like the handles, and the bolt 9 stands at right angles tothe cross-piecc D. The two arms f are connected on the rear side of thepivot by a segment, 1, provided in its middle with a recess, j, which isformed between two raised ribs formed on the upper side of the segment.

H represents the locking-disk arranged on the cross-piece D,and providedwith a central aperture through which the pivot-boltg passes.

h represents locking-bolts formed on the under side of thelocking-disk,and projecting through openings in the cross-piece D. The lower ends ofthe bolts 72 which project beyond the cross-piece D, are made conical ortapering, and enter similar recesses, i, formed in the upper side of thehook E, concentric with the pivotbolt 9, so that upon applyingsufficient force to the hook the locking-bolts are lifted out ofengagement with the hook, and the latter can be turned on thepivot-bolt, while the locking-bolts hold thehook in position againstaccidental displacement.

j represents a spring which surrounds the boltg and bears upon the diskH, in order to supply the necessary resistance against any force whichtends to lift the disk. The spring j is arranged in a casing, J, havingthe form of an inverted cup, and resting upon the cross piece 1), towhich the casing is secured by the pivot-bolt y.

K represents a lever, which is pivoted to the top of the casing J by thepivot-boltg,a11d which engages withits rear arm in the recess f" of thesegment f, while its front arm terminates in a pin, 7;.

L represents the jointer, which is made symmetrically on both sides ofits central line, so that it can be reversed, and which is provided witha socket, Z, by which it is attached to astem or shaft, Z. t The latterpasses through an opening or socket, m, formed in the beam A, in whichthe stem is held against longitudinal displacement by a collar, m. Thelatter is seated in a recess, m, formed in the beam A, and intersectingthe socket m. The collar m is secured to thestem by a set-screw, andbears against the front and rear sides of the recess m", so that thecollar and the stem are held against longitudinal movement when thecollar is secured to the stem. Upon loosening the stem on the collar thestem and the jointer attached thereto can be adjusted longitudinally onthe plow. ing rearwardly, so that the stem can assume variousinclinations in the socket, thereby raising or lowering the .jointer,the recess m being made sufficiently high to permit the collar m to moxe with the stem in adjusting the inclination of the latter. The angularposition of the stem Z is controlled by a bearing, N, secured to therear side of the beam. The bearingN is provided with an opening, through which the rear end of the stem passes, so that the stem iscompelled to move up and down with the bearing N, while it is free tomove lengthwise through the opening in the bearing.

r The latter is secured to the beam by a bolt, n,

which passes through an-elongated opening, I", in the bearing, andpermits the latter to be raised and lowered on the beam, thereby raisingand lowering the rear end of the stem 1, and lowering or raising thejointer correspondingly.

M represents a coupling-sleeve pivoted to the rear end of the stem l bya transverse bolt, m, and N is a rod which connects the front end of thelever K with the sleeve M, The lower end of the rod N is provided'withan eye, in which the pin of the lever K engages, and the upper end ofthe rod N slides in openings formed in the sleeve M.

For the purpose of reversing the plow, the operator presses against thatarm of the duplex hook E which is not engaged with the mold-board insuch manner as to disengage the opposite arm from the mold-board. Thelatter and the point are now free to be swung underneath the standard tothe opposite side of the plow. This being done, the first-mew tioned armof the duplex hook is now engaged with the mold-board and secures thesame in position. This turning movement of the hook E on its pivotcauses the lever K to be turned also, and the movement of the latter istransmitted by the rod N and coupling M to the stem of the jointer, soas to reverse the latter. By this simple turning of the hook E themoldboard is secured in position and the jointer properly adjusted atthe same time. The locking-recesses i in the upper side of the hook Eare arranged in two groups or sets, one for each locking position of thehook, so that up- The socket m is made flaron releasing the disk H thehook can be turned until it reaches the opposite locking position, 65when the disk H drops and the pins h engage in the other set oflocking-recesses, thereby locking the hook in this position againstaccidental displacement.

I am aware that the jointer and mold-board have been simultaneouslyreversed by means of movable handles connected with the jointer andlocked to the mold-board by a double hook, and I do not claim suchconstruction.

I claim as my invention- 1. The combination, with the plow-beam andstandard provided with handles 0 G,"rigidly secured thereto, of areversible jointer secured to a shaft journaled in the plow-beam, a reversible mold-board, a duplex hook, E, mounted on a stationary pivot,and mechanism, substantially as described, whereby the jointershaft isconnected with the duplex hook, and the jointer is reversed by swingingthe hook on its pivot, substantially as set forth.

2. The combinatiomwith the plow-beam and standard provided with handles0 .(J, rigidly secured thereto, of a reversible jointer secured to ashaft, a reversible moldboard, a duplex hook, E, mounted on a stationarypivot, and a pivoted lever, K, rod N, and coupling M, whereby the motionof the hook is trans mitted to the shaft of the joi nter, substantiallyas set forth.

3. The combination, with the pivoted book E, provided withlocking-recesses i, of the movable locking-disk H. provided withtapering locking-pins h, a perforated fixed support, D, through whichthe pins h move, and a spring, j, bearing upon the disk H, substantiallyas set forth.

4. The combination, with the pivoted hook E, provided withlockingrecesses i, of the movable locking-disk H, provided with taperinglocking-pins h, a perforated fixed support, D, spring j, easing J, andpivot-bolt 9, substantially as set forth.

5. The combination,with the beam or standard provided with a socket, m,and recess m, of the jointer L, secured to a stem, 1', and a collar, m,seated in the recess m, and secured adjustably to the stem 1',substantially as set forth.

6. The combination,with the beam or standard provided with a socket, m,enlarged rearwardly, of a jointer, L, secured to astem, l, passingthrough the socket m, and a bearing, N, supporting the rear end of thestem 1, and made vertically adjustable on the 4 beam or standard,substantially as set forth.

\Vitness my hand this 14th day of January,
